Or, prepend your commands at the shell CLI with "catch".  Something

    Bad = "yo, I cause pain".
    {ok, D} = dets:open_file(...).
    catch dets:lookup(Bad, my_key).
    catch dets:lookup(D, my_key).

... would prevent using the bad DETS table name from a cascade that
kills the shell CLI process than then closes the DETS table so that the
second lookup() attempt also fails.
